Calculate the LCM of 238,561,211,668

Given numbers are 238,561,211,668

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 238,561,211,668 is 553502796.

Find LCM of 238,561,211,668 with Prime Factorization


2 238, 561, 211, 668
17 119, 561, 211, 334
7, 33, 211, 334

Multiply the prime numbers at the bottom and the left side.

2 x 17 x 7 x 33 x 211 x 334 = 553502796

Therefore, the lowest common multiple of 238,561,211,668 is 553502796.

LCM Formula to Find Lowest Common Multiple of 238,561,211,668

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

238 x 561 x 211 x 668 = 18819095064

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

238 : 1, 2, 7, 14, 17, 34, 119, 238

561 : 1, 3, 11, 17, 33, 51, 187, 561

211 : 1, 211

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,561,211,668, is 1.

Now, the common factors can be found like this.

238:2x 7x 17

561:3x 11x 17

211:211

668:2x 2x 167

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 17 = 34

Therefore, the value for common factors is 34.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 18819095064/(1x34)

LCM = 18819095064/34

LCM = 553502796

Thus, we can understand that the LCM of 238,561,211,668 is 553502796.
